Amd's next-generation gpus could include displayport 2. 0 for 8k hdr games

There’s reason to believe that AMD can support the updated DisplayPort 2.0 specification with its next-generation RDNA 3-based graphics cards. If that happens, it could pave the way for 8K games without HDR compression, though that we are getting a little ahead of ourselves.

What’s at stake here are half a dozen new patches to AMD’s open source unified graphics driver for Linux (AMDGPU). He last patches (via Phoronix) come from AMD and add support for the DisplayPort 2.0 protocol.

The Video Electronics Standards Association (VESA) actually announced the The DisplayPort 2.0 specification was just over two years ago, and then followed it last year by adding an alternative mode (or high mode) standard to the mix to provide "perfect interoperability with the new specifications." USB4 published by the USB Implementers Forum (USB-SI). "

Alt mode basically allows all DisplayPort 2.0 features via a USB Type C connector, to split the bandwidth between video and data, if desired. And it's the bandwidth gain that's very important here.

DisplayPort 2.0 can provide a maximum payload of up to 77.37 gigabits per second in four lanes (up to 19.34 Gbps per lane), compared to 48 Gbps for HDMI 2.1. Without introducing compression, it is enough to feed up to a 10K resolution screen at 60Hz or an 8K display at 60 Hz with full color HDR at 4 bps 4: 4: 4.

The introduction of the so-called Display Stream Compression (DSC) allows for even higher resolutions and refresh rate combinations: there's enough bandwidth to get a 16K (15360 x 8460) display at 60Hz, also with a full color HDR of 4 bps at 4: 4: 4.

Both the monitor and the graphics card need to support DisplayPort 2.0 to take advantage of all this bandwidth. At present, neither exists in the consumer space. Looks like that could change next year, though.

In January, VESA told our friends at Tom & # 39; s Hardware that the pandemic delayed the timeline to get DisplayPort 2.0 products into the wild.

“What caused a delay is the situation of Covid-19,” explained Craig Wiley, VESA representative. "What usually happens is that companies get together and check hardware to check for interoperability between a PC and a screen. In fact, VESA has test events we call PlugTests, usually two or three a year. But no we had none in 2020. This has caused a delay in debugging and development. "

At the time, Wiley said he expects DisplayPort 2.0 products to arrive sometime in the second half of this year. If that’s the case, it almost definitely means we’re seeing DisplayPort 2.0 monitors coming first, as we have no knowledge of any major GPU releases planned for this year.

Looking to the future, AMD's next-generation GPUs could support DisplayPort 2.0, and we wouldn't be surprised if Nvidia adopted the standard next year as well. Of course, the other side of the equation is to provide enough GPU power to drive high-resolution gaming.

We recently got to the point where it’s possible to make games comfortable in 4K, although it still requires high-end hardware and / or additional sampling routines like Nvidia’s DLSS 2.0 and AMD’s FidelityFX Super Resolution (Intel will also implement some sort of technique super sampling with its upcoming GPU Alchemist).

So while DisplayPort 2.0 will provide another path to 8K gaming, it remains to be seen if next year’s GPUs will live up to the task.
